Rev. 2.3_00
CMOS SERIAL E2PROM
S-93C46A/56A/66A
The S-93C46A/56A/66A is high speed, low power 1K/2K/4K-bit E 2 PROM with
a wide operating voltage range. It is organized as 64-word ×16-bit,
128-word×16-bit, 256-word×16-bit, respectivly. Each is capable of sequential
read, at which time addresses are automatically incremented in 16-bit blocks.
The instruction code is compatible with the NM93CS46/56/66.
„ Features
y Low power consumption
Standby : 1.0 µA Max. (VCC=5.5 V)
Operating : 0.8 mA Max. (VCC=5.5 V)
: 0.4 mA Max. (VCC=2.5 V)
y Wide operating voltage range
Read/Write : 1.8 to 5.5 V
y Sequential read capable
y Endurance : 106 cycles/word
y Data retention : 10 years
y S-93C46A : 1K bits NM93CS46 instruction code compatible
y S-93C56A : 2K bits NM93CS56 instruction code compatible
y S-93C66A : 4K bits NM93CS66 instruction code compatible
